Definitions

  • This invention relates to a navigation data receiving device according to the preamble part of claim 1.
  • the navigation system that radio waves from the GPS (global positioning system) satellite is received to detect the present position, and the present position thus detected is displayed on the display map, has been popularly employed as a mobile system. Recently, attention has been paid to the advantage that this system is applied to the portable personal computer (PC).
  • GPS global positioning system
  • the hard system In the case of the portable type, being different from the mobile type, for the purpose of miniaturization and weight reduction, the hard system is limited; that is, the hard disk capacity is not so large.
  • map data are down-loaded from the CD-ROM to the PC' hard disk.
  • all the parts of the map data read out of the CD-ROM are not down-loaded; that is, only a necessary part is selectively down-loaded.
  • EP-A-0 786 646 discloses a system and method for distributing updated navigation data used in in-vehicle navigation systems.
  • the vehicle owners of such navigation systems may visit a plurality of so-called "local repositories" from time to time where they can obtain updated navigation data.
  • Both the repositories and the in-vehicle navigation systems have the possibility to be updated with actual navigation data.
  • the update of the local repositories can be done either by administrator technicians who access them to update their geographical data sets or electronically via a communication link by modem with a central or regional facility.
  • the Patent abstract of Japan JP 09166450 A discloses a navigation equipment which contains a modem and a communication device.
  • This navigation equipment contains a GPS which transmits the current position information of a vehicle via a communication line to server machines found in the intemet.
  • the server machines hereupon transmit map data including the position of the vehicle to the navigation equipment.
  • WO-A-97 35 166 discloses a remote data collection system used in vehicles, which includes directional sensors such as one or more cameras for sensing a characteristic of interest and providing sensor data. This system further includes a global positioning system (GPS) receiver and a disk storage unit. A processing unit determines geographic data referenced to the sensor data in response to the GPS data. These geographic data are stored in the disk storage unit.
  • GPS global positioning system
  • the premise of the present invention resides in the novel navigation system that data base is formed which can supply map data over wide areas, and part of the map data is received the user through internet and down-loaded to the portable PC's hard disk.
  • An object of the invention is to provide a navigation data receiving device in which internet is utilized to distribute map data, whereby, even with a portable personal computer small in hard disk capacity, navigation service can be obtained over wide range.
  • a navigation data receiving device for a portable personal computer comprising:
  • a PC card incorporating a GPS block has been put in practical use. In view of an available space, it is sufficiently possible to build a modem block adapted to receiving navigation data in the same PC card. Hence, with a portable PC, merely by using only one PC card, not only the GPS data but also the navigation data can be received.
  • the navigation data include restaurant data and town data in addition to map data.
  • FIG. 1 is a block diagram showing a PC card, which is an embodiment of the invention.
  • FIG. 1 is a block diagram of a PC card showing the embodiment of the invention.
  • reference numeral 1 designates a PC card; 2, a GPS block; 3, a modem block; 4, a PC card inter face; 5, a PC card connector; 6, a GPS receiving antenna connecting terminal; 7, a telephone line connecting terminal; and 8, a portable telephone connecting terminal.
  • the GPS block 2 comprises: a GPS converter 21 adapted to convert a radio wave from the GPS satellite, which is received through a GPS receiving antenna 9 connected to the terminal, into a signal low in frequency band; a GPS decoder 22 adapted to decode the output of the converter 21 to output position data; and a CPU 23 adapted to process the position data outputted by the decoder 22.
  • the modem block 3 comprises: a telephone line interface 31 adapted to access internet with a portable telephone set connected to a telephone line connected to the terminal 7 or to the terminal 8; a modem IC 32 which utilizes internet connected through the telephone line interface, to receive navigation data from a navigation system data base; and a CPU 33 adapted to process navigation data demodulated by the modem IC 32.
  • the PC card interface 4 is to connect the CPU 23 of the GPS block 2 and the CPU 33 of the modem block 3 to a PC body (not shown).
  • the PC card connector 5 is to connect the PC card interface 4 to the PC body.
  • the PC body is of a hard design necessary for a general portable PC; that is, it comprises: a hard disk which down-loads navigation data, a RAM which reads necessary data from the hard disk and stores them temporarily; a display which displays a map image according to the aforementioned navigation data, or the present position mark according to GPS data; and a keyboard adapted to externally give instructions.
  • the modem block 3 has a function of transmitting signals to internet. Hence, the modem block 3 may be so designed that the present position data obtained from the GPS system is transmitted to the internet, to receive navigation data with the present position data as reference.
  • the PC card 1 may be a PCMCIA card. Alternatively, an RC232C port may be utilized therefor. And an infrared ray interface may be utilized.
